Eu preciso ter a capacidade de enviar e-mails usando a interface da Web do Gmail, mas eles parecem ter origem em meu próprio domínio, em vez de se originarem em um endereço do Gmail. Para fazer isso, o gmail solicita as informações do meu servidor smtp (url, conta, etc.) e confirma que, de fato, tenho permissão para enviar e-mails do domínio usando meu próprio servidor smtp (postfix, hospedado no meu linode).
A resposta do Gmail é "Seu outro provedor de e-mail está respondendo muito lentamente. Tente novamente mais tarde ou entre em contato com o administrador do seu outro domínio para obter mais informações." - não pode obter mais detalhes do que isso deles.
Eu configurei o Postfix, o Dovecot, o MariaDB para o Centos 7 de acordo com O tutorial do Linode para o Centos 7 e eu tentei adaptar às minhas necessidades algumas das instruções encontradas em um tutorial do Chuan Ji intitulado" Custom domain emails com postfix e gmail "(ie eu gerei um single arquivo .pem baseado no conselho lá, incluindo o nome do meu servidor smtp como o nome comum - mail.tcs-usa.com no certificado para tornar o gmail feliz).
Eu sou capaz de enviar e-mails com o Thunderbird usando o postfix como meu servidor smtp e tenho o postfix configurado para encaminhar e-mails recebidos endereçados a qualquer endereço no meu domínio) para minha conta do gmail. Isso funciona perfeitamente bem. Eu também verifiquei o meu servidor smtp com mxtoolbox.com e também encontra tudo em ordem.
Estou incluindo abaixo um trecho do log do postfix. A única coisa que salta para mim é "match_list_match: mail-yk0-f169.google.com: sem correspondência" na linha 11 e outra na linha 12.
Agradeço antecipadamente por toda sua ajuda e desculpas se estou incluindo muita informação, mas já estou nisso há dois dias e não chego a lugar nenhum.
Alex
